The project area is hosted in the crystalline basement complex
rocks of southwestern Nigeria and forms a part of the Upper Proterozoic rocks of the Ilesha schist belt.
A Pre-Cambrian-Infra-Cambrian Basement Complex
, composed of eroded igneous and metamorphic rocks including gneiss, schist, meta-volcanics and meta-sediments.
While very ancient rock strata are exposed in a few places within Egypt, including the first Nile cataract at Aswan, almost everywhere this very hard 'basement complex
' is overlain by softer sandstone that, in turn, is covered by limestone of various types, which could be utilized for building (while the harder rocks, like granite and basalt, could be used for statues, sarcophagi and smaller objects).
All that has been retained of the grand original Edwardian building are the outer facades, while the interiors are being ripped off and redone to even create a vast basement complex
The surface geology of the area is dominated by the basement complex
rocks which are overlain by thin layer of superficial deposits
The method of radial average power spectrum is used to determine the depths of volcanic intrusions, depths of the basement complex
and the subsurface geological structures.
When the property is completed, it will be a home of substance comprising three reception rooms, a large kitchen/ dining/family room, basement complex
with gym, bar and cinema room, master bedroom with dressing room and en suite, seven further bedrooms and six further bathrooms.
For example, the study area in this paper is underlain by crystalline basement complex
The area is underlined by Precambrian rocks typical of the basement complex
of Southwestern Nigeria  and it covers about 150 m x 150 m.
Now in its final iteration, Mobile Homestead is docked to a "mother ship" that forms the rest of Kelley's house, including a two-car garage and a bi-level basement complex
made up of small rooms accessible only via various ladders.
First stage works have seen the completion of the basement complex
for staff use.
Although the area is a basement complex
area, the soil that eventually stand as the support, must have resulted from the weathering of the basement rocks present in the areas.
